Update: BC1193 is installed. Never figured out what the O-rings were for.

My lower fitting has two o-rings that I can see and they look smaller then the ones supplied. It does look like one of these would fit on the shoulder inside the quick release fitting but I didn't notice one there when I took it apart. Maybe I lost it? First time doing a radiator on an XJ...

Just received my new BC1193. Came with the proper fittings but it also came with a pair of o-rings. Any idea what they are for? My plan was to just put some teflon tape on the fittings and screw them in but it looks like I'm suppose to do something with the o-rings.

Thanks for your insight and details on the mods you had to make. I'm very familiar dealing with the idiosyncrasies of aftermarket parts and it sure is helpful to have a heads up on these types of things. I haven't change out a radiator in a while and just trying to make sure all my bases or...

I need to order a radiator this weekend and the Champion BC1193 is at the top of my list. Does it come with the trans cooler fittings? One picture on the website shows two elbow fittings, shouldn't the top port be a nipple type fitting?

I haven't really done anything to solve this issue yet because I keep my Scangauge II hooked up all the time and I can monitor the temp. It seems accurate and the dash gauge should be reading the same signal. An example of the problem is that the other day I was sitting in traffic on a warm day...

98 4.0 AW4 My in dash temp gauge is only half working. It operates normally up to 210F but doesn't register past that. I have a scangauge hooked up to OBD II that I've monitored the temp with the last couple of years but I think it's time to see if I can fix it. Anybody aware of a fix for the...

I would like to see that service bulletin. My efan definitely kicks in at over 220F

My 98 XJ manual says something like this about electric fan operation Electric cooling fan 4.0L: With or without A/C request the electric fan will come on only when the coolant temperature is at least 106° C (223° F), and will remain on until the coolant temperature drops to 103° C (217° F) or...

Get some wheel chocks then.

Have you inadvertently turned on the dome lights with the headlamp switch. Rotate the headlamp switch clockwise to turn off the dome light. Edit: Just noticed this was already addressed. But I'll leave it.

If the temperature is normal when you're moving and only overheats when idling check and replace the fan clutch. Oil pressure needs to be checked with a mechanical gauge at operating temperature.
